llvm-3.0: FTBFS under MIPS & MIPSEL

[Sylvestre Ledru <sylvestre@debian.org>]

Hello,

In order to have llvm-3.0 into testing, I have to fix a last build
failure under  MIPS & MIPSEL.

The full mipsel build log is available here:
https://buildd.debian.org/status/fetch.php?pkg=llvm-3.0&arch=mipsel&ver=3.0-5&stamp=1324350511
[1]

The error is the following:
/build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/build-llvm/Release/bin/llvm-tblgen -I  /build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/lib/Target/X86 -I  /build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/include -I  /build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/include -I  /build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/lib/Target -gen-disassembler -o  /build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/build-llvm/lib/Target/X86/Release/X86GenDisassemblerTables.inc.tmp /build/buildd-llvm-3.0_3.0-5-mipsel-jV6EnH/llvm-3.0-3.0/lib/Target/X86/X86.td

[pages of similar errors]

Note that I haven't been able to reproduce the bug with the two
porterboxes (gabrielli & eder).

Any ideas? I am available for testing.

LLVM 2.9 was building fine [2].

Thanks,
Sylvestre

[1] Please note that mips log is available here:
https://buildd.debian.org/status/fetch.php?pkg=llvm-3.0&arch=mips&ver=3.0-5&stamp=1324342896
but since it is a parallel build, it is pretty boring to read.
